摘要： An arousal-level determining apparatus (100) includes a generating unit (120), a calculating unit (130), an identifying unit (140), and a determining unit (180). The generating unit (120) generates heartbeat-interval variation data, which indicates changes in heartbeat interval, on the basis of heartbeat signals indicating subject's heartbeats. The calculating unit (130) applies a band-pass filter, which allows passage of a certain range of frequencies, to each frequency band in the heartbeat-interval variation data while changing the frequency band, and calculates spectral density with respect to each frequency band applied with the band-pass filter. The identifying unit (140) identifies a feature point corresponding to a spectral density peak in the calculated spectral densities in the frequency bands. The determining unit (180) determines subject's arousal level on the basis of the identified feature point.

摘要： A drive assist device according to an embodiment includes an environment detection unit, a list generation unit, a gaze detection unit, a risk evaluation unit, and an output control unit. The environment detection unit detects an environment around a vehicle driven by a driver. The list generation unit generates a hazard list of an object to be a hazard on the basis of the detected environment. The gaze detection unit detects a gaze of the driver. The risk evaluation unit evaluates a risk regarding driving of the driver for each object included in the hazard list on the basis of a frequency at which the object included in the hazard list is included in a field of view of the driver based on the detected gaze. The output control unit outputs drive assist information corresponding to the object having the evaluated risk that is equal to or larger than a threshold.

摘要： An awakening-degree determining device (100) according to the present embodiment acquires heartbeat signal data on the subject from a heartbeat detecting unit and detects heartbeat interval data. The awakening-degree determining device (100) calculates the power spectral density that corresponds to each frequency by using the heartbeat interval data, calculates a peak P and a bottom B, and calculates a state index S. Then, the awakening-degree determining device (100) plots the movement of the state index on an awakening-degree determination graph and determines the degree of awakening of the subject on the basis of the position of the state index S.

摘要： A noise processing apparatus measures a first potential difference signal, between a first electrode that is arrange at a location other than a steering unit in an apparatus and a second electrode that is used as a reference electrode, and measures a second potential difference signal, between the second electrode and a third electrode that is arranged on the steering unit in the apparatus. The noise processing apparatus calculates the intensities of the first potential difference signal and the second potential difference signal at predetermined intervals. The noise processing apparatus calculates the difference between the intensities of the first potential difference signal and the second potential difference signal calculated at the predetermined intervals. The noise processing apparatus corrects the first potential difference signal or the second potential difference signal at the predetermined intervals by using the calculated difference such that the intensities of the first potential difference signal and the second potential difference signal are canceled out. The noise processing apparatus calculates a differential signal indicating the difference between the first potential difference signal and the second potential difference signal at the predetermined intervals by using the corrected potential difference signal. The noise processing apparatus outputs the differential signal.
